UB242

UNISONIC TECHNOLOGIES CO., LTD UB242 Preliminary CMOS IC LITHIUM-ION/POLYMER BATTERY PROTECTION IC „ DESCRIPTION 6 5 4 UTC UB242 is a series of lithium-ion / lithium-polymer rechargeable battery protection ICs incorporating high accuracy voltage detection circuits and delay circuits. UTC UB242 is suitable for protection of single cell lithium-ion / lithium polymer battery packs from overcharge, over discharge and over current. The ultra-small package and less required external components make it ideal to integrate the UTC UB242 into the limited space of battery pack. 1 2 3 „ * * * * * * * * * * FEATURES Wide supply voltage range: Ultra-low quiescent current: Ultra-low power-down current: Overcharge detection voltage: Overcharge release voltage: Over discharge detection voltage : Over discharge release voltage: Over current detection voltage: Short circuit detection voltage: Charger detection voltage: Reset resistance for over current protection: VDD=1.8V~9.0V IDD=3.0μA (VDD=3.9V) IPD=0.1μA (VDD=2.0V) VOCU=4.200V~4.400V VOCR=4.005V~4.225V VODL=2.15V~3.00V VODR=2.32V~3.10V VOI1=0.05V~0.20V VOI2=1.35V (Fixed) VCH=-0.7V RSHORT＞500kΩ SOT-26 * Delay times are generated by an internal circuit.
